Then I rubbed the dirty marks with the wet, soapy washcloth until the dirty marks were gone. Got them today, and it?s all we are waiting on to leave. The large works well for me--roomy/loose, but doesnt swallow me--. They slide with ease to change the configuration. They fit a touch loose, but he?s ok w it. Like other wired head phones the head phone jack is the weak point of the design since they tend to flex and bend causing issues with connection points of the wires going onto the headphone jack. Without the rubbing, would have been 5 stars. They fit me as expected and I feel very very comfortable to put them on. Mala calidad. Im with T-Mobile and most bands are supported but still had to create a custom APN (look it up) to send/receive txts and mms txts.
